Description

CROSS-REFERENCE TO RELATED APPLICATION
This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2020-0138573, filed on Oct. 23, 2020 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.
BACKGROUND 1. Field
The disclosure relates to a vehicle and an antenna for the vehicle, and more particularly, to a vehicle including an antenna embedded in a spoiler and an antenna apparatus mounted on a spoiler for the vehicle.
2. Description of the Related Art
Generally, a vehicle refers to an apparatus of transportation that travels on a road or track using fossil fuel, electricity, or the like as a power source.
Recently, in addition to simply transporting goods and personnel, vehicles generally include audio and video apparatuses so that drivers may listen to music and watch videos while driving, and a navigation apparatus that displays a route to a destination for a driver is also widely installed.
For this reason, the necessity for the vehicle to communicate with an external apparatus is increasing.
For example, in the case of a navigation function guiding the vehicle on a route to the destination, the vehicle may receive a GPS signal from a global positioning system (GPS) satellite in order to determine the location of the vehicle. The vehicle may receive a radio broadcast signal and/or a multimedia broadcast signal to reproduce a broadcast sound and/or image. In addition, the vehicle may communicate with a mobile communication base station and/or another vehicle through a mobile communication service.
An antenna for communication with external apparatuses may be provided in the vehicle. In particular, since the frequency of the GPS signal, the frequency of the broadcast signal and the frequency of the mobile communication signal are different from each other, a plurality of antennas having different shapes are provided in the vehicle.
On the other hand, the conventional antenna is assembled to the roof of the vehicle in the form of a shark fin or a pole and is exposed to outside. As a result, restrictions arise in the design and size of the antenna. For example, the antenna may include an AM/FM radio antenna, a global navigation satellite system (GNSS) antenna, a distributed matching antenna (DMA), and a mobile communication antenna. The four antennas are integrated and thus a restriction of design and size for safety reasons occurs.
SUMMARY
An aspect of the disclosure is to provide a spoiler for a vehicle in which an antenna of the vehicle is embedded and to provide a vehicle including an antenna embedded in the spoiler.
An aspect of the disclosure is to provide a spoiler in which a plurality of antennas operating at different frequencies are embedded and to provide a vehicle including the same.
An aspect of the disclosure is to provide a spoiler in which an antenna apparatus is embedded, and which is capable of mounting a plurality of antennas for mobile communication and to provide a vehicle including the same.
A vehicle according to an aspect of the disclosure may include a spoiler mounted on or near a rear of the vehicle and an antenna apparatus provided inside the spoiler. The spoiler may include a spoiler body configured to include a seating portion, on which the antenna apparatus is seated, and a cover configured to cover the seating portion. The antenna apparatus may include: a casing; a cable electrically connected to an electric apparatus in the vehicle; a pole type antenna provided outside the casing; and an antenna assembly electrically connected to the cable and the pole type antenna. The antenna apparatus may also include at least one semiconductor element and a plurality of patch antennas mounted on a printed circuit board.
The casing may include an upper case; a lower case; and a sealing pad disposed between the upper case and the lower case.
The upper case may be provided with a seating space in which the pole type antenna is seated.
The seating space may be provided with a plurality of supports configured to support the pole type antenna.
The pole type antenna may include a spring coil, a shell surrounding the spring coil, and a metal thread electrically connected to the spring coil and inserted into the upper case.
The upper case may include a pole insert coupled to the metal thread and the pole insert may be electrically connected to the antenna assembly.
The sealing pad may be provided with a coupling groove into which the upper case is inserted.
Each of the lower case and the sealing pad may be provided with a fixing hole into which a bolt for fixing the antenna apparatus to the spoiler body may be inserted.
The plurality of patch antennas may include a first mobile communication antenna installed on one end of the printed circuit board and a second mobile communication antenna installed on another end of the printed circuit board.
The plurality of patch antennas may include a global navigation satellite system (GNSS) antenna and a SiriusXM (SXM) antenna stacked on the GNSS antenna.
